When the variable frequency mobile air conditioner is used for refrigerating, water in the air is condensed into water drops and flows to the chassis through the water receiving disc.
Fig. 1 is a schematic flowchart of a control method for an inverter mobile air conditioner according to an embodiment of the present disclosure. As shown in fig. 1, the process of controlling the inverter mobile air conditioner includes:
step 101: and acquiring the current water level height value of the variable-frequency mobile air conditioner chassis in the refrigeration running state.
The variable frequency mobile air conditioner has a compressor, an exhaust fan, an electric heater, an evaporator, a condenser and other devices in the body. And, mobile air conditioner is when the refrigeration operation, when being in the refrigeration running state promptly, can condense into the drop of water with the moisture in the air, flow to the chassis through the water collector in, like this, can save the comdenstion water in the chassis, if the comdenstion water in the chassis is too much, or the chassis has filled the comdenstion water, probably cause the compressor to shut down, consequently, need carry out real-time or timing detection to the water level in the chassis, accessible water level detection device acquires the water level height value on chassis, wherein, current moment, the water level height value that acquires is current water level height value promptly.
Step 102: and determining a current compressor control strategy matched with the current water level height value and a current motor control strategy of a water pumping motor positioned in the chassis.
In the frequency conversion mobile air conditioner, there is a water-beating motor arranged on the chassis, the condensed water in the chassis can be beaten into water mist by the water-beating motor to attach to the condenser for heat exchange, thus, the energy efficiency can be effectively improved, but, the condensed water in the chassis is too much, or the chassis is filled with the condensed water, the compressor may be stopped, and therefore, if the current water level height value of the chassis is higher, the compressor needs to be operated in a frequency reduction mode, thus, the speed of generating the condensed water can be reduced, and the water-beating motor needs to be operated at a higher rotating speed, thus, the speed of beating the condensed water into water mist can be accelerated, thereby, the water level of the condensed water in the chassis can be rapidly reduced, and the probability of the compressor stopping phenomenon caused by the too high condensed water level is reduced, therefore, in some embodiments, the current compressor control strategy matched with the current water level height value is determined, and the current motor control strategy of the water-beating motor in the chassis includes: under the condition that the height value of the current water level is greater than or equal to the early warning water level value, determining a frequency reduction operation strategy as a current compressor control strategy, and determining a first motor control strategy operating at a first rotating speed as a current motor control strategy; under the condition that the height value of the current water level is smaller than the early warning water level value, determining a frequency reduction removal operation strategy as a current compressor control strategy, and determining a second motor control strategy operating at a second rotating speed as a current motor control strategy; wherein the second rotation speed is less than the first rotation speed.
Wherein, early warning water level value, first rotational speed, second rotational speed can be according to the performance of air conditioner, and air conditioner place geographical position information and season information confirm to, the operation of falling frequency can have multiple mode, include: down conversion at a fixed value or at a set rate, etc.
For example, if the current water level height value is greater than or equal to the early warning water level value, the current compressor control strategy is determined to be a frequency reduction operation strategy of reducing the frequency by 10HZ each time, and the current motor control strategy is determined to be operated at 1000 revolutions. And if the current water level height value is smaller than the early warning water level value, determining that the current compressor control strategy is a frequency reduction removal operation strategy. Of course, after the frequency reduction operation is removed, the compressor can operate according to the target temperature and the current environment temperature value, and the water pumping motor can also operate by adopting the existing related technology.
In some embodiments, the water level height value of the condensed water in the chassis, different water level height values corresponding to different compressor control strategies and different motor control strategies can be further subdivided, and the corresponding relationship between the water level height value and the control strategies corresponding to the compressor and the water pumping motor respectively can be determined according to the performance of the air conditioner, the information of the geographical position of the air conditioner and the season information.
Table 1 shows the correspondence between the water level height values and the control strategies corresponding to the compressor and the water pump motor, respectively, according to the embodiment of the present disclosure.
TABLE 1
Thus, in some embodiments, as shown in table 1, determining a current compressor control strategy that matches the current water level height value, and a current motor control strategy for a water motor located in the chassis, includes: and under the condition that the current water level height value is greater than or equal to the shutdown water level value, determining a low-frequency strategy which operates at the lowest frequency corresponding to the current environment temperature value as a current compressor control strategy, and determining a second motor control strategy which operates at the highest rotating speed as a current motor control strategy. The shutdown water level value is greater than the early warning water level value, and the early warning water level value can be full water level or close to full water level, so, the water level of the condensate water in the chassis is very high, the production of the condensate water needs to be reduced, and the speed of the condensate water quickly converted into water mist is accelerated.
Of course, in case that the current water level height value is less than the stop water level value, the lowest frequency operation of the compressor should be released. At this time, the compressor may be operated according to the target temperature value and the detected temperature between the current ambient temperature values. Alternatively, in some embodiments, as shown in table 1, in the case that the current water level height value is less than the shutdown water level value and greater than or equal to the early warning water level value, the down-conversion operation strategy is determined as the current compressor control strategy, and the first motor control strategy operating at the first rotation speed is determined as the current motor control strategy.
The early warning water level value is lower than the shutdown water level value, but is still higher, so the compressor can carry out frequency reduction operation, the speed of generating condensed water is reduced, the first rotating speed is lower than the highest rotating speed, but is higher, the condensed water can be consumed quickly, and the probability of shutdown of the air-conditioning compressor is further reduced.
Certainly, under the condition that the current water level height value is smaller than the early warning water level value, the frequency reduction operation needs to be removed, and at the moment, the compressor can operate according to the target temperature value and the temperature between the detected current environment temperature values. Or, in some embodiments, as shown in table 1, when the current water level height value is greater than or equal to the set water level value and less than the early warning water level value, the frequency limiting strategy that operates at the first frequency limit is determined as the current compressor control strategy, and the third motor control strategy that operates at the second rotation speed is determined as the current motor control strategy.
Setting the water level value can indicate that excessive risk exists in the condensed water in the chassis, at the moment, the operation of the compressor can be controlled by a limited frequency, the speed of generating the condensed water is stable, and the second rotating speed is lower than the first rotating speed, so that the energy consumption and the speed of consuming the condensed water can be considered.
Of course, when the current water level height value is smaller than the set water level value, the frequency-limited operation can be removed, and then the compressor can operate according to the target temperature value and the detected temperature between the current environment temperature values. The water fetching motor can also operate according to corresponding strategies of the related technology.
Step 103: and respectively controlling the operation of the compressor and the operation of the water pumping motor according to the current compressor control strategy and the current motor control strategy.
And determining the current motor control strategy and the current motor control strategy, namely controlling the operation of the corresponding compressor and the water fetching motor. Such as: the current compressor control strategy is a frequency reduction operation strategy, namely the compressor can be controlled to operate at the speed of 8HZ per time of frequency reduction. The current motor control strategy is a second motor control strategy which operates at the highest rotating speed, and the water pumping motor can be controlled to operate at the highest rotating speed.
Therefore, in the embodiment, when the variable-frequency mobile air conditioner is used for refrigerating, the operation frequency of the compressor and the rotating speed of the water pumping motor can be controlled according to the water level height value of the condensed water in the chassis, so that the probability of compressor shutdown caused by the fact that the condensed water in the chassis is full is reduced, the mobile air conditioner does not need excessive intervention, the water level height and the water level consumption capacity are intelligently adjusted, and the mobile air conditioner can continuously, stably and efficiently refrigerate.
In some embodiments, the water level alarm process is performed in case that a duration of the current water level height value greater than or equal to the shutdown water level value is greater than a set time. The water level height value of the condensed water in the chassis exceeds the shutdown water level value all the time, a set time lasts, the water level alarm processing can be carried out, and therefore a user can receive the drained water.
Of course, in some embodiments, a full water level value may be directly set, and in case that the current water level height value is greater than the full water level value, the operation of the compressor is stopped, and the water level alarm process is performed, wherein the full water level value is greater than the stopped water level value.
Of course, there are various ways to handle the water level alarm, including: photoelectric mode, voice mode, character mode, etc.
The following operation flows are integrated into a specific embodiment to illustrate the control process for the variable frequency mobile air conditioner provided by the embodiment of the invention.
In one embodiment of the disclosure, a water level sensor is configured in an air conditioner chassis, and an early warning water level value is stored according to the performance of an air conditioner.

Step 204: and controlling the compressor to operate according to the temperature difference between the target temperature value and the acquired current environment temperature value, controlling the water pumping motor to operate at the rotating speed of 800, and returning to the step 201.
Therefore, in the embodiment, when the variable-frequency mobile air conditioner operates in a refrigerating mode, and the current water level height value in the chassis is larger than or equal to the early warning water level value, the compressor can operate in a frequency reduction mode, the speed of generating the condensed water is reduced, the water pumping motor operates at a high rotating speed, the condensed water can be consumed quickly, and the probability of stopping the air conditioner compressor is further reduced.
In an embodiment of the present disclosure, a water level sensor is disposed in the air conditioner base plate, and the corresponding relationship shown in table 1 is stored.

And (5) transferring to the step.
Step 304: is the current water level height determined to be greater than or equal to the warning water level value? If so, go to step 305, otherwise, go to step 309.
Step 305: and determining a frequency reduction operation strategy of 10HZ reduction each time as a current compressor control strategy, and determining a first motor control strategy operating at a first rotating speed of 100 revolutions as a current motor control strategy. Proceed to step 309.

Step 309: and respectively controlling the operation of the compressor and the operation of the water fetching motor according to the current compressor control strategy and the current motor control strategy.
Step 310: is it determined whether the duration of the current water level height value being greater than or equal to the shut-down water level value is greater than the set time? If yes, go to step 311, otherwise, go back to step 301.

Therefore, in the embodiment, when the variable-frequency mobile air conditioner is used for refrigerating, the operation frequency of the compressor and the rotating speed of the water pumping motor can be controlled according to the water level height value of the condensed water in the chassis, and different water level height values correspond to different compressor control strategies and motor control strategies, so that the shutdown probability of the air conditioner compressor is reduced, the energy consumption is also considered, the intelligence of the air conditioner is further improved, and the continuous, stable and efficient refrigeration of the mobile air conditioner is realized.

Thus, when the current water level height value is greater than or equal to the shutdown water level value, according to table 1, the third determining unit 422 in the determining module 420 may determine the low frequency strategy operating at the lowest frequency corresponding to the current ambient temperature value as the current compressor control strategy, and determine the second motor control strategy operating at the highest rotation speed of 1100 as the current motor control strategy. If the current water level height value is less than the shutdown water level value but greater than or equal to the early warning water level value, the first determining unit 421 may determine the down-conversion operation strategy of decreasing by 10HZ each time as the current compressor control strategy, and determine the first motor control strategy of operating at the first rotation speed of 100 revolutions as the current motor control strategy. If the current water level height value is less than the early warning water level value but greater than or equal to the set water level value, the fifth determining unit 423 may determine the frequency limiting strategy that operates at the first frequency limit as the current compressor control strategy and determine the third motor control strategy that operates at the second rotation speed of 900 revolutions as the current motor control strategy. If the current water level height value is less than the set water level value, the sixth determining unit 424 may determine that the target strategy operating according to the target temperature is determined as the current compressor control strategy.
Thus, the control module 430 may control the operation of the compressor and the water motor, respectively, according to the current compressor control strategy and the current motor control strategy. And, if the current water level height value is greater than or equal to the shutdown water level value and the duration is greater than the set time, for example, 3min, the first warning module 440 may perform the voice water level alarm processing.
